About Valtti Plus Kesto Semi-Transparent Wood Stain and Finish for Exterior Wood.

Tikkurila Valtti Plus Kesto is an extremely durable waterborne semi-transparent wood stain/finish for use on exterior wood. 

Suitable for exterior log surfaces, smooth and sawn wood surfaces, impregnated and thermally modified wood.

It forms a tough water repellent surface and protects the wood from weathering and retards the adverse effects of moisture and UV degradation.

Available in a very wide range of semi-transparent colours, Tikkurila Valtti Plus Kesto penetrates and enhances the natural beauty of wood.  

It is ideal for timber cladding, weatherboarding, windows, fascias, fencing, sheds, garden furniture, log cabins, etc.

Surface Preparation and Application.

Surfaces must be clean, dry, and free from grease, dirt, oil, wax, loose material and surface contamination. Use Tikkurila Mould Removal Solution and Cleaning Solution.

Fill cracks, joints, nail holes, with a good quality wood filler. 

Ensure that existing glossy, previously stained and filled surfaces are thoroughly sanded to ensure adequate penetration in to the surface of the wood. 

Make sure that timber cladding, weather boarding and timber glazing beads, etc., are adequately fastened with non-corrosive fixings. 

Particular attention with regards to preparation should be given to wood such as Oak, Teak, Cedar, Douglas Fir, Mahogany and Idigbo, which contain oil and water-soluble

tannins which may impair the drying, hardening or adhesion and possibly cause staining of surface.

When coating new woodwork it is recommended that a priming coat of Valtti Base should be applied to all exterior wood which has not been pre-treated or vacuum impregnated with an approved wood preservative.

Apply liberally on end-grain.

Valtti Plus Kesto is not recommended for use with silicone sealant or linseed oil putty.

Application and Thinning

Methods: brush or spray.
For airless spray: use a 0.009” – 0.013” spray tip.
Note: Synthetic polyester and nylon paint brushes are best suited for the application of Valtti Plus Kesto.

All surfaces to be painted must be dry, the moisture content of the wood below 20%, the temperature of the air at least +50C, and the relative humidity of the air below 80%.
